IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 94,780, dated September14, 1869.

-To all whom it may concern Beit known that I, NICHOLAS SElB-ERT, of thecity and county ot' Nevada, State of Galifornia, have invented aSelilndicating Lubricator; and do hereby declare the followingdescription and accompanying drawings are suiicient to enable any personskilled in the art 01 science to which it most nearly appertains to makeand useV my said invention' or improvement without further invention orexperiment.

My invention relates to an improved lubricator, more especially adaptedlor use in places where it is necessary to have a constant supply of oilor tallow; and the novelty consists in making it seliindicating, as`well as preventing` waste.

The apparatus is in the form of a cylinder haring a piston, and apiston-rod extends from it through one end of the cylinder. The cylinderis 'filled with melted tallo'w, or other lubricant, through a globe orother cock, the tallow filling all the space at one side of the piston,which is pushed back to the extreme end of the cylinder.

A cock admitssteam behind the piston and forces it slowly f'orward,whileanother cock at the opposite end ol the cylinder allows the tallow topass to its destination.

A small scale extends from the front cylinder-head parallel with thepistonrod, and the divisions show at what rate the piston is moving, andconsequently the amount of the lubricant used per hour. This can beregulated by the, steam-cock giving a greater or less pressure, asrequired.

Referring lo the accompanying drawings for a fuller explanation of myinvention, Figure l is a longitudinal vertical section ot' my apparatus.Fig. 2 is an end view.

Similar letters of reference in each of the figures indicate like parts.

A is a cylinder within which the piston B travels.

. The pistonrod O extends through the front cylinder-head, being packedso as to not leak, and may carry an index at its end.

A scale, D, extends from the front cylinderhead, parallel with the lineof motion of the rod C, and by the speed with which the index on the1rod passes the divisions on the scale,

the amount of oil or tallow used per hour is estimated.

A feeding-cup, E, is placed on the top of the cylinder, and through thisthe cylinder is lilled, the piston being pushedrback to the cxtreme end.

A small escape-cock, F, allows the air to pass, so that the oil willreadily enter the cylinder.

At the back ot' the. cylinder is a cock, Gr, which admit-s the steam bythe pressure of which the piston is forced along. This cock is made withapassage, a, through which the steam passes, andashort one, c, extendinghalt' through the key, at right angles with the passage a.

When it is necessary to discharge any accumulation of water fromcondensation of steam, the cock is turned so that the'passage e connectswith the interior of' the cylinder, when one side of the passage a willcommunicate with the escape-pipe d, the steam-passage bcing thus cutoff.

The oil or tallow is forced by thepiston out through the cock H, fromwhich it passes to its destination. The Forms ot' cock to he used arenot of especial importance, although I have made use of globe cocks formy present illustration as being the most economical and tight.

The amount of oil used in a given time may be seen by a glance at thescale D, which also shows when the supply is exhausted, and by means ofthe cocks the pressure is so regulated as to insure a constant supply.

The apparatus is not liable to getout o' repair, and the saving in thequantity ot' the lubricant, as well as in wear, is ,very great.

In applying my invention to locomotives, or wherever the lubricant isneeded at more than one point, two pistons may be used in the samecylinder, and steam being admitted between them, they are graduallyforced toward the ends of the cylinder, thus supplying the lubricantthrough diierent cocks to the respective points of consumption.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is Y l. The arrangement of the cylinder A,provided with a piston, B, rod C, and scale D,

vwith reference to the cup E and coek H, sub- In witness whereof I havehereunto set my stantially as and for thepurpose set fortli. hand andseal.
